Abstract
DATEM synthesis was optimized to produce samples with high amounts of active components for breadmaking. Therefore, the parameters of a standard procedure were modified systematically and the amounts of the major components in the resulting samples were determined by high-performance liquid chromatography. Standard solutions of the three most active components were used for identification and quantitation. Molten reactions between monoacylglycerols and diacetyltartaric acid anhydride at low temperature (100°C) had a positive effect on the formation of active components, especially after the addition of sodium acetate as a catalyst. The yield of active components increased up to 88% compared to ∼60% obtained by a standard procedure. The highest yield of the major components was obtained by using tetrahydrofuran as a solvent and pyridine as a catalyst. Under these conditions more than 90% of the DATEM sample were components with high baking activity.
